Can a patient stage 1 papillary thyroid cancer with BRAF mutation positive live more than 20 years (she is 51 years old)? Thank you very much!

Yes. Papillary thyroid cancer is very common and some people do not even know they have it as small tumors may be found on autopsy when they die of something else. Generally tumors are graded by how ugly they look to the pathologist and how far they've spread. Your tumor has also been molecularly characterized. There are new treatment options available. Please discuss with your oncologist.
